Extraordinary waterfront residence offering panoramic river views from nearly every room. Rebuilt in 2009, this approximately 3,400 sq ft custom home is perfectly positioned along the Connetquot River with direct access to the Great South Bay, delivering a seamless blend of luxury and coastal living. The interior features an open and sun-filled layout designed to maximize water views, with expansive windows and effortless flow for both everyday living and entertaining. This home offers 4 bedrooms and 3.5–4 bathrooms, with generous living spaces and refined finishes throughout. The outdoor setting is equally impressive, featuring 177 feet of bulkhead, a private dock with boat lift (recently updated cables), and multiple tiers of waterfront entertaining space. A heated saltwater in-ground pool and spa complete the resort-style backyard. Set on approximately 0.53 acres in one of Great River’s most sought-after locations, this property offers privacy, tranquility, and unmatched access to the water. A rare opportunity to own a true waterfront retreat with exceptional views, boating access, and timeless design.
